Calling all big families!!

We are considering ttc number 5 and I am a little nervous. #1 was a 24+ hour labor but not too painful since I had so much time to slowly get used to contractions. #2 was 3 hours and basically a dream labor and delivery....Also wasn’t very painful. #3 was 3 hours and pretty damn painful from the first few minutes of contractions. #4 was a total of 53 minutes from start to finish and by far the most painful labor, delivery, and recovery. I’m terrified if we have another my labor will be so quick I won’t make it to a hospital and it wouldn’t be that big of a deal if I wasn’t so high risk and had a history of preterm labor. Did your deliveries become shorter with each subsequent pregnancy?
